State Tankless Water Heaters Review

State tankless water heaters are gas-powered appliances that
are
designed to heat potable water, on demand, in endless and continuous
supply in residential and light commercial applications. This review is
about State tankless and it covers the main features
and benefits.

All
the water heaters from State are wall-hanging, small in size and with
the nice attractive design, so they can be installed anywhere inside
the house, for point-of-use and whole-house water heating. The advanced
built-in features allow high efficient, long lasting and reliable
service during the time of its 15-year warranty, even longer.

There
are two types of tankless appliances from State; condensing and
non-condensing, both with an indoor and outdoor installation. Indoor
models are installed only inside the building, while outdoor are
designed ventless, for the outside installation, on the exterior wall
or in
the recess box.

The indoor models use the vent pipe to get the
fresh combustion air in and move the exhaust gases out. Some of the
indoor models can be converted to use direct venting. The use of PVC,
ABS and other cheap materials make condensing venting cheaper than
venting found on non-condensing.

Features

Air-fuel ration sensor

State
tankless water heaters are equipped with the air-fuel ratio sensor that
adjusts the proper fan motor speed and therefore allow proper air/fuel
mixture for ideal gas combustion. This is what maximizes the efficiency
and reduces the emission of greenhouse gases.

Safety features

The tankless units are
very safe. If only one of the requirements is not met or one element
doesn't work, the water heater will turn off. Safety features include
the high limit switch to prevent exposure to high temperatures,
overheat cut off and internal freeze protection system that turns on if
the temperature of surrounding air drops and increase the risk of
freezing.

Increased water flow option

The water flow can
be increased by grouping two or more water heaters into one system.
This is available through the Easy-Link system
that allows connection
of up to 4 units for 510, 510U and 540H series and Multi-unit
system
that allows connection of up to 20 units for 510U and 540H series, in
residential applications.

Modulation

Modulating gas control valve
adjusts the gas flow rate so the water heater can use only the amount
of energy that is required to meet the set temperature, so the energy
loss is minimal.

Types and Models

Non-condensing series

All
non-condensing
tankless water heaters from State have the energy factor of 0.82, which
makes them Energy Star compliant and high efficient with reduced gas
emission (“U” series are Ultra Low NOx models).

Non-condensing models
from 510 series have one heat exchanger only that is made tough to
withstand high thermal stress and last long. It is made of strong HRS35
copper alloy that is durable and stronger than HE found in water
heaters of other manufacturers.

Every unit from non-condensing
group has the remote controller included and built-in temperature
controller to monitor and adjust the temperature and for
troubleshooting.

110 series

State tankless water heaters from 110 series
include GTS-110 and GTS-110U models, which have the smallest size and
capacity. With the maximum water flow rate of 6.6 GPM, tankless heaters
can provide enough hot water for one to two showers, or smaller homes,
apartments, condos, cottages and offices.

310 series

310 series includes
GTS-310 and GTS-310U models, which, with the water flow of 8.0 GPM, are
able to supply up to three-bath homes.

510 series

510 series consist of the
GTS-510 and GTS-510U models, or standard and low NOx models that have
the maximum water flow rate of 10 GPM making it good for homes with 2-4
bathrooms.

Condensing series

Condensing
water heaters are also Energy Star but provide more savings due to the
ultra-high energy factor of 0.91.

Condensing
models have two heat exchangers where the secondary element is made of
heavy-duty stainless steel that is resistant to corrosion and acidic
condensation of the flue gases. There are several condensing models
available: standard 320 and 520 and ultra-low NOx models; 240H, 340H
and 540H.

As it can been seen from the above, State tankless water
heaters are about technology, efficiency, savings and flexibility. The
models can be used in variety of applications mainly due to its
flexibility in venting installation, when used in recirculation
systems, combination with storage tanks, home heating system, solar
heating, as one unit or combined in multiple system.
